Scarlett Johansson has revealed that her glamorous image is an elaborate act. The sexy Black Dahlia actress uses her glam image to hide behind and to protect herself from intrusion into her private life. She's actually quite a casual gal apparently, and likes her flats and trainers, (but she certainly knows how to dress up for those big occasions...) Scarlett said in an interview with InStyle: "I like the façade of glamour. Being a person in the public eye is a performance in itself...To me, the great thing about being an actress is walking around the film set and going into a costume truck and seeing the wigs and special effects make-up." |
